Solok Regency is an administrative area located in West Sumatra that is currently carrying out disaster mitigation programs. Mostly, major infrastructure such as the Solok Local Government Buildings Complex, school facilities, hospital buildings, and many dense residential buildings are scattered over this area. One notable event happened on September 30, 2009, which forced the local government to take serious prevention steps to reduce casualties and damages in the future. Furthermore, there is a need to develop a comprehensive study to analyze the seismic hazards by determining the value of Peak Ground Acceleration (PGA) at the bedrock. The analysis was carried out using the Probability Seismic Hazard Analysis (PSHA) by calculating several seismic sources towards Solok regency by a radius of 500 kilometers from the Arosuka area for a 2475-year return period. The result showed a PGA value of 1.052g on Arosuka, Solok regency, while the Openquake platform shows the range of PGA values varies from 0.576g – 1.368g. The PGA values were then visualized into a seismic hazard map using a geographic information system (GIS). In addition, these scientific results are used as basic information to estimate the seismic vulnerability to support the disaster risk reduction program in West Sumatra.
